In an exemplary embodiment, as illustrated in FIG. 6 with continuing reference to FIGS. 1-5, a method 44 of building the custom mattress 14 includes determining customer-specific mattress parameters in step 46, building a prototype mattress in step 48, and testing the prototype mattress in step 50. In step 52, it is determined whether the customer approves of the prototype mattress. If not, then the prototype mattress is modified in step 54, and the steps 50, 52 and 54 are repeated until the customer approves of the prototype mattress in the step 52. If the customer does approve of the prototype mattress in the step 52, then a custom mattress is built according to the specifications of the approved prototype mattress in step 56. As used herein, in an exemplary embodiment, the term “customer” refers to two persons who plan to regularly sleep on the custom mattress 14. In several exemplary embodiments, the term “customer” may also refer to one person who plans to regularly sleep alone on the custom mattress 14, or three or more persons who plan to regularly sleep on the custom mattress 14.

In an exemplary embodiment, as illustrated in FIG. 7 with continuing reference to FIGS. 1-6, to determine customer-specific mattress parameters in the step 46 of the method 44, the zonal weights of the customer are determined in step 46 a. Before, during or after the step 46 a, the customer's sleep habits and patterns are determined in step 46 b. Before, during or after the steps 46 a and 46 b, objective body measurements of the customer are taken in step 46 c. After the steps 46 a, 46 b and 46 c, a core cartridge profile is determined in step 46 d, with the core cartridge profile being at least partially based on the zonal weights, sleep habits and patterns, and objective body measurements of the customer.

In an exemplary embodiment, as illustrated in FIG. 8 with continuing reference to FIGS. 1-7, to determine the zonal weights of the customer in the step 46 a, a test bench, such as an air mattress 58, is provided, with the air mattress 58 including air bladders 58 a-58 h, each of which is fluidicly isolated from the other air bladders. The air bladders 58 a-58 h define zones 58 i-58 p, respectively, of the air mattress 58. Each of the air bladders 58 a-58 d is operably coupled to a measurement unit 60, and each of the air bladders 58 e-58 h is operably coupled to a measurement unit 62. In operation, to determine the zonal weights of the customer in the step 46 a, one of the two persons collectively defined as the customer lies down across the zones 58 i-58 p of the air mattress 58. The measurement unit 60 measures the respective pressure differentials in the air bladders 58 a-58 d, which pressure differentials are generated as a result of the one of the two persons collectively defined as the customer lying down across the zones 58 i-58 l, thereby determining the zonal weights in the zones 58 i-58 l. Similarly, the measurement unit 62 measures the respective pressure differentials in the air bladders 58 e-58 h, which pressure differentials are generated by the one person laying down across the zones 58 m-58 p, thereby determining the zonal weights in the zones 58 m-58 p. In several exemplary embodiments, instead of, or in addition to pressure differentials, the measurement units 60 and 62 measure force differentials, displacements, other physical parameters generated as a result of the one person lying down across the zones 58 i-58 l, and/or any combination thereof. After the zonal weights for the one of the two persons collectively defined as the customer is determined, the zonal weights for the other of the two persons collectively defined as the customer is determined, in accordance with the foregoing, thereby completing the step 46 a.

In several exemplary embodiments, instead of, or in addition to air, the air bladders 58 a-58 h may be filled with liquid, gel, other types of gases, other types of fluidic materials, other types of materials, and/or any combination thereof.

In an exemplary embodiment, as illustrated in FIG. 9 with continuing reference to FIGS. 1-8, to determine the customer's sleep habits and patterns in the step 46 b, a questionnaire or survey 64 is provided that includes a series of questions 66, which includes a question as to which side of the body a person sleeps on, whether a person sleeps with a pillow, etc. Each of the two persons collectively defined as the customer takes a separate survey for himself or herself, thereby completing the step 46 b. In an exemplary embodiment, in the step 46 b, in addition to, or instead of the each of the two persons collectively defined as the customer taking a separate survey for himself or herself, the each of the two persons takes a survey for the other person.

In an exemplary embodiment, as illustrated in FIG. 10 with continuing reference to FIGS. 1-9, to take objective body measurements of the customer in the step 46 c, measurements of each of the persons collectively defined as the customer are taken, including, for example, a wrist measurement 68 a, a shoulders measurement 68 b, a height measurement 68 c, a hips measurement 68 d, a waist measurement 68 e, and/or any combination thereof.

In an exemplary embodiment, to determine the core cartridge profile in the step 46 d, the zonal weights of the customer determined in the step 46 a, the sleep habits and patterns of the customer determined in the step 46 b, and the objective body measurements of the customer taken in the step 46 c, are considered and provide the basis for the core cartridge profile for the custom mattress 14, which specifies the optimum specific pressure resistance value and/or firmness/support characteristic for each of the core cartridges 26 a-26 p.

In an exemplary embodiment, the zonal weights in the zones 58 i-58 p for the one of the two persons collectively defined as the customer are relatively significant factors in specifying the optimum pressure resistance values and/or firmness/support characteristics for the core cartridges 26 a-26 h, respectively. Similarly, the zonal weights in the zones 58 i-58 p for the other of the two persons collectively defined as the customer are relatively significant factors in specifying the optimum pressure resistance values and/or firmness/support characteristics for the core cartridges 26 i-26 p, respectively.

In an exemplary embodiment, as illustrated in FIG. 12 with continuing reference to FIGS. 1-11, to build the prototype core unit 16 in the step 48 a, the prototype core cartridges 26 a-26 p are selected in step 48 aa according to the core cartridge profile previously determined in the step 46 d, the selected prototype core cartridges 26 a-26 p are provided in step 48 ab to a build area or build bay 70, and the prototype core unit 16 is built in step 48 ac using the selected prototype core cartridges 26 a-26 p.

In an exemplary embodiment, as illustrated in FIG. 13 with continuing reference to FIGS. 1-12, to select the prototype core cartridges 26 a-26 p in the step 48 aa, the prototype core cartridges 26 a-26 p are selected according to the core cartridge profile determined in the step 46 d of the step 46 of the method 44. That is, the specific pressure resistance values and/or firmness/support characteristics of the selected prototype core cartridges 26 a-26 h match, or most nearly match, the optimum specific pressure resistance values and/or firmness/support characteristics of the core cartridges 26 a-26 h, respectively, specified by the core cartridge profile determined in the step 46 d, with these optimum values and/or characteristics being based on the other customer-specific parameters determined in the step 46, namely the zonal weights determined in the step 46 a, the sleep habits and patterns determined in the step 46 b, and the objective body measurements taken in the step 46 c of one of the persons collectively defined as the customer; likewise, the specific pressure resistance values and/or firmness/support characteristics of the selected prototype core cartridges 26 i-26 p match, or most nearly match, the optimum specific pressure resistance values and/or firmness/support characteristics of the core cartridges 26 i-26 p, respectively, specified by the core cartridge profile determined in the step 46 d, with these optimum values and/or characteristics being based on the other customer-specific parameters determined in the step 46, namely the zonal weights determined in the step 46 a, the sleep habits and patterns determined in the step 46 b, and the objective body measurements taken in the step 46 c of the other of the persons collectively defined as the customer.

In an exemplary embodiment, if the customer is one person who plans to regularly sleep alone on the custom mattress 14, then the specific pressure resistance values and/or firmness/support characteristics of the selected prototype core cartridges 26 a-26 h are equal to the specific pressure resistance values and/or firmness/support characteristics of the selected prototype core cartridges 26 i-26 p, respectively.

In an exemplary embodiment, as illustrated in FIG. 13 with continuing reference to FIGS. 1-12, to provide the selected prototype core cartridges 26 a-26 p in the step 48 ab after the prototype core cartridges 26 a-26 p are selected in the step 48 aa, the selected prototype core cartridges 26 a-26 p are placed on a cart 72, and the cart 72 is moved to the build bay 70.

The prototype core cartridge 26 a is removably disposed in the region 22 e of the prototype encasement 22, and is adjacent the sides 22 c and 22 a of the prototype encasement 22. The prototype core cartridge 26 h is removably disposed in the region 22 e of the prototype encasement 22, and is adjacent the sides 22 d and 22 a of the prototype encasement 22. The prototype core cartridges 26 b-26 g are removably disposed between the prototype core cartridges 26 a and 26 h, and are adjacent the side 22 a of the prototype encasement 22. As a result, the portion of the prototype core cartridge profile defined by the prototype core cartridges 26 a-26 h matches, or nearly matches, the corresponding portion of the core cartridge profile determined in the step 46 d for the one of the two persons collectively defined as the customer. Similarly, the prototype core cartridge 26 i is removably disposed in the region 22 e of the prototype encasement 22, and is adjacent the sides 22 c and 22 b of the prototype encasement 22. The prototype core cartridge 26 p is removably disposed in the region 22 e of the prototype encasement 22, and is adjacent the sides 22 d and 22 b of the prototype encasement 22. The prototype core cartridges 26 b-26 g are removably disposed between the prototype core cartridges 26 i and 26 p, and are adjacent the side 22 b of the prototype encasement 22. As a result, the portion of the prototype core cartridge profile defined by the prototype cartridges core 26 i-26 p matches, or nearly matches, the corresponding portion of the core cartridge profile determined in the step 46 d for the other of the two persons collectively defined as the customer. The remainder of the prototype core unit 16 is built in accordance with the foregoing description of the core unit 16 and therefore these steps will not be described in further detail.

In an exemplary embodiment, as illustrated in FIG. 15 with continuing reference to FIGS. 1-14, to build the prototype topper unit 18 in the step 48 b of the step 48 of the method 44, the prototype topper cartridges 38 and 40 are selected in step 48 ba, and the prototype topper unit 18 is built in step 48 bb using the selected prototype topper cartridges 38 and 40.

In an exemplary embodiment, in the step 48 ba, the prototype topper cartridges 38 and 40 are selected based on the core cartridge profile determined in the step 46 d. In an exemplary embodiment, the prototype topper cartridge 38 is selected on the basis of the portion of the core cartridge profile determined in the step 46 d for the one of the two persons collectively defined as the customer. In an exemplary embodiment, the prototype topper cartridge 40 is selected on the basis of the portion of the core cartridge profile determined in the step 46 d for the other of the two persons collectively defined as the customer. In an exemplary embodiment, the prototype topper cartridges 38 and 40 are selected on the basis of the composition of, and/or the materials included in, the cushion panels 38 a and 40 a, respectively, which basis is informed by one or more of the customer-specific parameters determined in the step 46 of the method 44.

In an exemplary embodiment, as illustrated in FIG. 16 with continuing reference to FIGS. 1-15, to build the prototype topper unit 18 in the step 48 bb using the selected prototype topper cartridges 38 and 40, the prototype topper cartridges 38 and 40 are coupled together in accordance with the foregoing description of the topper unit 18, and are removably disposed in the region 36 e of the prototype encasement 36, which, in turn, is removably disposed in the region 34 af of the prototype cover 34. The remainder of the prototype topper unit 18 is built in accordance with the foregoing description of the topper unit 18 and therefore these steps will not be described in further detail.

In an exemplary embodiment, to couple the prototype topper unit 18 to the prototype core unit 16 in the step 48 c, the prototype topper unit 18 is coupled to the prototype core unit 16 in accordance with the foregoing description of the assembled condition of the mattress 14, thereby completing the step 48 of the method 44.

In an exemplary embodiment, as noted above, after the prototype mattress 14 is built in the step 48, the prototype mattress 14 is tested in the step 50. To test the prototype mattress 14 in the step 50, the one of the two persons collectively defined as the customer lies down across the prototype mattress 14 so that he or she lies down across the prototype cartridge topper 38 and the prototype core cartridges 26 a-26 h, and the other of the two persons collectively defined as the customer either simultaneously or subsequently lies down across the prototype mattress 14 so that he or she lies down across the prototype cartridge topper 40 and the prototype core cartridges 26 i-26 p.

In an exemplary embodiment, as noted above, it determined in the step 52 as to whether the customer approves of the prototype mattress 14. To determine whether the customer approves of the prototype mattress 14 in the step 52, customer feedback and response is elicited, and the customer's response to lying on the prototype mattress 14 is observed.

In an exemplary embodiment, as noted above, if the customer does not approve of the prototype mattress 14 in the step 52, then the prototype mattress 14 is modified in the step 54. To modify the prototype mattress 14, one or more of the prototype core cartridges 26 a-26 p are replaced, and/or one or more of the prototype topper cartridges 38 and 40 are replaced, in response to the elicited customer feedback and response, and/or in response to any observations of the customer's response to lying on the prototype mattress 14. As a result, the pressure resistance values and/or firmness/support characteristics of the prototype topper cartridges 38 and 40 and the prototype core cartridges 26 a-26 p, and thus the prototype mattress 14, are modified in response to the elicited customer feedback and response, and/or in response to any observations of the customer's response to lying on the prototype mattress 14.

In an exemplary embodiment, during the step 54, the respective labels 32 on the prototype core cartridges 26 a-26 p facilitate the easy and accurate identification of the respective types of the cartridges, and/or of the respective pressure resistance values and/or firmness/support characteristics of the cartridges.

In an exemplary embodiment, as noted above, the testing of the prototype mattress 14 in the step 50 is then repeated after modifying the prototype mattress 14 in the step 54. The steps 50, 52 and 54 are repeated until it is determined that the customer approves of the prototype mattress 14 in the step 52.

In an exemplary embodiment, as noted above, if the customer approves of the prototype mattress 14 in the step 52, then the custom mattress 14 described above with reference to FIGS. 1-5 is built in the step 56 according to the specifications of the approved prototype mattress 14. The core cartridges 26 a-26 p, and the topper cartridges 38 and 40, in the custom mattress 14 built in the step 56 are substantially identical to the prototype core cartridges 26 a-26 p, and the prototype topper cartridges 38 and 40, respectively, included in the prototype mattress 14 approved in the step 52.

In an exemplary embodiment, in the step 56, instead of the built custom mattress 14 and the prototype mattress 14 being different mattresses, the custom mattress 14 built in the step 56 is the same mattress as the prototype mattress 14 approved in the step 52.

In an exemplary embodiment, in the step 56, the custom mattress 14 is built in a delivery truck before, during or after transit to the delivery location of the custom mattress 14. In an exemplary embodiment, in the step 56, the custom mattress 14 is built in the build bay 70, and/or in a location proximate the build bay 70. In an exemplary embodiment, the custom mattress 14 is built in the step 56 at a retail location. In an exemplary embodiment, the custom mattress 14 is built in the step 56 at a location remote from either a retail location and/or the build bay 70. In an exemplary embodiment, the custom mattress 14 is built in the customer's bedroom.

In operation, in an exemplary embodiment, the custom mattress 14 rests on, and is supported by, the box platform 12. When the customer lies on the custom mattress 14, the core unit 16 provides support and comfort to the customer, and the topper unit 18 distributes the loading created by the customer lying on the custom mattress 14, thereby providing further comfort to the customer. The respective pluralities of springs 28 in the cartridges 26 a-26 p permit air flow therebetween and through the custom mattress 14, thereby permitting any heat transferred to the bed 10 to dissipate more easily and quickly. Since the custom mattress 14 has been built according to the above-described customer-specific parameters, the custom mattress 14 optimally fits the curvature of the customer's spine and thus provides a generally spine-neutral condition, optimally distributes the weight of the customer, and optimally accommodates the customer's soft tissue between the customer's spine and edge of skin.

During operation, in an exemplary embodiment, the topper cartridge 38 and the core cartridges 26 a-26 h enable the half portion of the bed 10 on which the one of the two persons collectively defined as the customer sleeps to optimally fit the curvature of the one person's spine and thus provide a generally spine-neutral condition, to optimally distribute the weight of the one person, and to optimally accommodate the one person's soft tissue between the spine and edge of skin; similarly, the topper cartridge 40 and the core cartridges 26 i-26 p enable the half portion of the bed 10 on which the other of the two persons collectively identified as the customer sleeps to optimally fit the curvature of the other person's spine and thus provide a generally spine-neutral condition, to optimally distribute the weight of the other person, and to optimally accommodate the other person's soft tissue between the spine and edge of skin. As a result, the custom mattress 14 accommodates the different physique, girth, weight, etc. of each of the two persons collectively defined as the customer, and further accommodates variations in physique, girth, weight, etc. along the body length of each of the two persons collectively defined as the customer.

During operation, in an exemplary embodiment, the frame 22 provides support characteristics that aid the customer as he, she or they ingress and egress to and from the sleeping surface of the custom mattress 14, and that prevent the customer from rolling off of the sleeping surface.

In an exemplary embodiment, as illustrated in FIG. 17 with continuing reference to FIGS. 1-16, a method 74 of retrofitting the custom mattress 14 includes detecting any variations in the performance characteristics of the custom mattress 14 and/or the customer's response thereto in step 76, identifying one or more of the core cartridges 26 a-26 p and/or one or more of the topper cartridges 38 and 40 in the custom mattress 14 in need of replacement in step 78, and replacing in step 80 the cartridges identified in the step 78.

In an exemplary embodiment, to detect any variations in the performance characteristics of the custom mattress 14 in the step 76, the customer detects a difference in how the custom mattress 14 feels and/or performs over a period of time, such as several years. In an exemplary embodiment, to detect any variation in the customer's response to the performance characteristics of the custom mattress 14 in the step 76, the customer detects their, his or her discomfort with the custom mattress 14 after the custom mattress 14 has been delivered to their, his or her home, or after at least portions of the mattress 14 have experienced wear and/or tear over time. In an exemplary embodiment, to detect any variation in the customer's response to the performance characteristics of the custom mattress 14 in the step 76, the customer wishes to change the feel of the mattress 14 for any reason including solely personal preference, regardless of whether the mattress 14 has experienced any type of wear and/or tear and/or performance degradation. In an exemplary embodiment, to detect any variation in the customer's response to the performance characteristics of the custom mattress 14 in the step 76, the customer detects their, his or her discomfort with the custom mattress 14 because of changes to the customer's physique, girth, weight, etc. over time.

In an exemplary embodiment, as illustrated in FIG. 18 with continuing reference to FIGS. 1-17, to identify one or more of the core cartridges 26 a-26 p and/or one or more of the topper cartridges 38 and 40 in the custom mattress 14 in need of replacement in the step 78, the respective types of the core cartridges 26 a-26 p and the topper cartridges 38 and 40 in the custom mattress 14 are determined in step 78 a, revised customer-specific parameters are determined in step 78 b, and, in step 78 c, the revised customer-specific parameters determined in the step 78 b are compared with the customer-specific parameters determined in the step 46 of the method 44 to determine whether the two sets of parameters are the same. If not, then it is determined in step 78 d which of the core cartridges 26 a-26 p and the topper cartridges 38 and 40 need to be replaced to meet the revised customer-specific parameters determined in the step 78 b. If it is determined in the step 78 c that the revised customer-specific parameters determined in the step 78 b are the same as the customer-specific parameters determined in the step 46 of the method 44, then the core cartridges 26 a-26 p and topper cartridges 38 and 40 are inspected or tested in step 78 e to identify which cartridges need replacement.

In an exemplary embodiment, to determine the respective types of the core cartridges 26 a-26 p in the custom mattress 14 in the step 78 a, the customer decouples the topper unit 18 from the core unit 16, unzips and pulls back the cover portion 20 b from the open-top portion 20 a of the cover, and visually determines the types of the core cartridges 26 a-26 p currently in the custom mattress 14 by visually noting the color coding and/or symbols on the respective labels 32, which are visible when the cover portion 20 b is unzipped and pulled back because the respective labels 32 wrap around the respective sides 30 a of the core cartridges. In an exemplary embodiment, to determine the respective types of the topper cartridges 38 and 40 in the custom mattress 14 in the step 78 a, the customer unzips and pulls back the cover portion 34 b from the open-top portion 34 a of the cover, and visually determines the types of the topper cartridges 38 and 40 currently in the custom mattress 14 by visually noting any labeling on the topper cartridges. In an exemplary embodiment, to determine the respective types of the core cartridges 26 a-26 p and the topper cartridges 38 and 40 in the custom mattress 14 in the step 78 a, the customer calls the retail seller of the mattress 14, who then looks up the types in a database and/or computer. In an exemplary embodiment, to determine the respective types of the core cartridges 26 a-26 p and the topper cartridges 38 and 40 in the custom mattress 14 in the step 78 a, the customer accesses a database over a network, such as a database accessible by a website over the Internet, and then looks up the types in the database. In an exemplary embodiment, to determine the respective types of the core cartridges 26 a-26 p and the topper cartridges 38 and 40 in the custom mattress 14 in the step 78 a, the customer visits the retail seller of the mattress 14, who then looks up the types in a database and/or computer.

In an exemplary embodiment, to determine the revised customer-specific parameters in the step 78 b, the step 46 described above is repeated, that is, the zonal weights of customer are determined, the customer's sleep habits and patterns are determined, objective body measurements of the customer are taken, and a core cartridge profile is determined.

In an exemplary embodiment, during the step 78, the steps 78 b, 78 c and 78 d are omitted.

In an exemplary embodiment, the execution of the method 74 is environmentally friendly because, instead of replacing the entire custom mattress 14, only the core cartridges 26 a-26 p that need to be replaced are replaced, and/or only the topper cartridges 38 and 40 that need to be replaced are replaced, thereby reducing waste and energy.

In an exemplary embodiment, the execution of the method 74 is economically advantageous because, instead of incurring the cost associated with replacing the entire custom mattress 14, only the costs associated with replacing the core cartridges 26 a-26 p that need to be replaced, and the topper cartridges 38 and 40 that need to be replaced, are incurred.
